Yes, they are a joke. And often dangerous. There's a troupe in Lincoln right now advertising as 'French' etc. Different profiles with the same number, fake pics. Usual stuff.
Shame, really, because there're probably some nice ones who we miss out on due to the actions of the horrible ones, which makes us boycott them as a group. They do have a nice look with the dark hair and good figures.
Personally, I had my best punts with Brazilians and British women.
